Preliminary crystallographic study of cyclohexadienyl dehydratase from Pseudomonas aeruginosa

Single crystals of cyclohexadienyl dehydratase from Pseudomonas aeruginosa have been obtained by vapour diffusion from ammonium sulphate solution (pH 6.0) at 4 degrees C. The crystals belong to the tetragonal space group P4(3)2(1)2 or P4(1)2(1)2 with a = b = 105.5 A and c = 165.0 A. The asymmetric unit contains at least one dimeric protein molecule with M(r) = 72 kDa. The crystals diffract to 3 A resolution and are suitable for an X-ray analysis.
